Question

我很茫然。我可以使水平滚动仅与html和css一起正常工作，但是当我介绍ngFor时，它拒绝产生相同的效果。是否有人对此有经验，或者知道如何解决此问题？

这是我无法使用的简单代码：

此示例产生一个垂直列表：

<div class="container" *ngFor="let item of items | async">
        <div class="scroll" scrollX="true">
         <span>{{item.ProjectEvent}}</span>
        </div>
    </div>

这将产生一个可以水平滚动的宽容器

 <div class="container" >
        <div class="scroll" scrollX="true">
            <span>item1</span>
            <span>item2</span>
            <span>item3</span>
            <span>item4</span>
            <span>item5</span>
            <span>item6</span>
            <span>item7</span>
            <span>item8</span>
            <span>item9</span>
        </div>
    </div>

两者的CSS相同：

.container {
  width: 100px;
  background-color: green;
  overflow: hidden; 
  white-space: nowrap;
  ::-webkit-scrollbar {
    display: none;
  }
  .scroll {
    overflow: auto;
  }
}

向我解释一下史波克先生！

谢谢您的帮助！

Answer 1

尝试在需要复制的实际元素上使用伪指令：

<div class="container">
    <div class="scroll" scrollX="true">
        <span *ngFor="let item of items | async">{{item.ProjectEvent}}</span>
    </div>
</div>

Answer 2

也许尝试

<ion-segment scrollable="true">
    <ion-segment-button value="friends">
      <ion-label>Friends</ion-label>
    </ion-segment-button>
</ion-segment>

Answer 3

使用flexbox：
